Nested Miller compensation in low-power CMOS design

First, new stability conditions for low-power CMOS nested Miller compensate d amplifiers are given in this brief. Then, an improved structure, which ta kes the advantages of a feedforward transconductance stage and a nulling re sistor, is introduced. Experimental results prove that the proposed structu re improves the frequency response, transient response, and power supply re jection ratio without increasing the power consumption and circuit complexi ty.
